"WITNESSES- I v v r a? I UNITED STATES PATENT OFFIC NORMAN C. BASSETT, OF LYNN, MASSACHUSETTS, ASSIGNOR TO THE GENERAL ELECTRIC COMPANY, OF NEW YORK.

MOTOR-SUSPENSION.

SPECIFICATION forming part of Letters Patent No. 556,488, dated March 1'7, 1896. Application filed November 27, 1895. Serial No, 570,307- (No model.)

To all whom it may concern:

Be it known that I, NORMAN O. BASSETT, a citizen of the United States, residing at Lynn, in the county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Motor=Suspensions, (Case N o. 286,) of which the following is a specification.

My invention relates to motor-suspensions for electric or other cars, and has for its object to provide a suspension which shall be simple, cheap, and easy of construction, strong enough to sustain the motor readily, and which shall sustain substantially the entire weight of the motor independent of its connection with the axle of the truck. It is of course designed, as in all modern equipments of the class described, to flexibly support the motor.

In other constructions devised by me-such, for instance, as that shown in my Patent No. 527,927, issued October 23, 1894--I have supported the motor on side bars parallel with the truck-frame, and in some instances by a cross-bar resting upon these side bars. This suspension has become known in the trade as the side-bar suspension. It is to provide a construction which shall embrace the advantages of the one disclosed in that patent, (these advantages being pointed out therein,) and yet shall be simpler and cheaper, that I have made my present invention, which will be better understood from the accompanying drawings, in which- Figure 1 is an end elevation with the truckframe side bars in section, and Fig. 2 is a plan of the motor suspended according to my invention.

In Fig. 1, A A are the side bars of the truckframe; B B, the wheels; 0, the axle D, the gear-case, and E the motor. All of these parts are old and well understood in the art.

E is the lid over the commutator, which is also a common construction.

Upon the front of the motor (by which I mean that part of it farthest removed from the axle) are lugs I I, preferably east upon the motor-casing, although they may be made in any other way. These lugs engage with a bar or yoke F passing along the front of the motor and having its ends spring-supported upon the side bars of the truck-frame, which also, as is cnstomary, are spring-supported by the pedestals, which are of common construction.

The springs supporting the bar F are shown at G, and a plate or washer Gsurmounts them,

.the whole being held together by studs G.

other forms of spring than the one indicated.

In many cases a rubber block would be sufficient, or an elliptical spring or any other form giving a flexible mounting to the bar or yoke F of the construction.

By the construction described the axle C is practically free to move independently of the motor E, which tips about its armature-shaft as a center, inasmuch as the supports of the yoke F are practically in that line, substantially the entire weight of the motor being supported by the bar. The track is relieved from hammer-blow either from the weight or the inertia of the motor, the advantages of the arrangement being pointed out in my patent before referred to.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. A suspension for car-motors comprising a truck-frame, a wheeled axle mounted in the frame, a motor geared to the axle, and a support for the other end of the motor consisting of a bar or yoke so bent as to be supported upon the truck-frame at substantially the plane of the center of gravity of the motor.

2. A suspension for car-motorscomprising a truck-frame, a wheeled axle mounted in the frame, a motor sleeved upon and geared to the axle, and a spring-support for the other end of the motor, consisting of a bar or yoke bent so as to be supported upon the truckframe at substantially the plane of the center of gravity ofthe motor;

3. A suspension for car-motors, comprising a flexibly-supported truck-frame, a Wheeled axle mounted in the frame, a motor sleeved upon and geared to the axle, and a springsupport for the other end of the motor, con sisting of a bar 01' yoke bent'so as to be supported by springs upon the truck-frame at 10 substantially the plane of the center of gravity of the motor.

In witness whereof I have hereunto set my hand this 20th day of November, 1895.
